Dayco Automatic Belt Tensioner Assembly (MPN: 89288)

Engineered for optimal performance and durability in serpentine belt systems.

The Dayco Automatic Belt Tensioner Assembly is designed to maintain consistent tension on serpentine belt drives, which are essential for powering various engine accessories. Utilizing an original flat spring design, this tensioner minimizes operating range variations, thereby reducing the risk of premature accessory bearing failure caused by excessive tension when a new belt is installed. Additionally, it addresses issues of belt noise and slippage that can arise from low tension as the belt stretches and wears over time.

Constructed with a heavy-duty cast aluminum spring case, the Dayco tensioner is built to resist cracking and fatigue, ensuring longevity and reliability. The assembly features a lubricated nylon pivot tube bushing and spring bushing, which contribute to quieter operation. A PTFE strip within the spring enhances abrasion resistance, while a rubber 'O' ring seals against dust and grime, protecting the internal components from harmful contaminants.

This tensioner is compatible with serpentine belt systems and is designed to meet OEM specifications, making it a suitable replacement for worn or damaged units. The use of high-quality materials, such as glass-filled polymer for the pulley, ensures that the tensioner can withstand the demands of critical torque requirements while maintaining optimal performance.
